Learning Resources for Kotlin

Learning a new language is always a good investment in the modern era but learning the right language can change your career and how you live your professional life. It can unlock a lucky door into your career.

Kotlin is an open-source, statically typed, a general-purpose programming language that runs on JVM. It is introduced by JetBrains, the official designer of the most intelligent Java IDE, named IntelliJ IDEA. It combines object-oriented programming and functional features into a unique platform that can give you the pleasure you feel when you are learning to program and it helps you to get your things done. Kotlin's main advantage is the JVM, it means that even as a new language, it has a better range of libraries and a better runtime than just about everything else. Kotlin is basically like writing Java in Swift syntax, you get all the niceties of Java, but write it in a language more like Swift in that it has a lot of syntactic sugar, type inference, and some cool features. Some of the topmost features of Kotlin are:

  • Open Source - Kotlin is open source under Apache License.
  • Interoperable with Java - You can use Kotlin programs inside Java project and vice-versa.
  • Tool Friendly - You can choose any Java IDE to write Kotlin program.
  • Safe - Since it is a statically typed language, it gives more flexibility to catch errors at run time.
  • Easy To Learn - It's easy to learn and understand.
  • Concise - It removes so many boilerplate codes as compared with Java.
